摘要： Disclosed are a centrifugal micro-fluidic structure for measuring glycated hemoglobin, a centrifugal micro-fluidic device for measuring glycated hemoglobin, and a method for measuring glycated hemoglobin. According to the disclosure, immunosorbent assay and affinity measurements are simultaneously conducted using only a single device in order to detect hemoglobin variants or interfering substances and, therefore, the detected results are applied to analysis of measurement results so as to eliminate and/or compensate for, or calibrate errors in measurement of, glycated hemoglobin, thereby more accurately measuring the glycated hemoglobin.

摘要： A microfluidic device to meter an accurate amount of fluid is provided. The microfluidic device includes a chamber configured to accommodate a fluid therein, an inlet channel connected to the chamber to supply the fluid into the chamber, and an outlet channel connected to the chamber and provided separately from the inlet channel. The outlet channel is configured such that after the chamber is filled with a predetermined amount of the fluid introduced through the inlet channel, any additional amount of the fluid introduced into the chamber in excess of the predetermined amount exits the chamber through the outlet channel.

摘要： A microfluidic device having a chamber with a fluid discharge configuration is provided. The microfluidic device includes a platform including a chamber configured to accommodate a fluid therein. The chamber includes an inner sidewall and an outer sidewall disposed outwardly from the inner sidewall in a radial direction of the platform. The outer sidewall includes a first point located closest to a center of the platform, and a second point located farthest from the center of the platform. A distance from the center of the platform to an arbitrary third point on the outer sidewall between the first point and the second point increases from the first point to the second point, so that the fluid near the first point is guided to the second point by centrifugal force during rotation of the platform.
